 NSS is available under the Mozilla Public License, version 2, a copy of which

 is below.

 Note on GPL Compatibility

 -------------------------

 The MPL 2, section 3.3, permits you to combine NSS with code under the GNU

 General Public License (GPL) version 2, or any later version of that

 license, to make a Larger Work, and distribute the result under the GPL.

 The only condition is that you must also make NSS, and any changes you

 have made to it, available to recipients under the terms of the MPL 2 also.

 Anyone who receives the combined code from you does not have to continue

 to dual licence in this way, and may, if they wish, distribute under the

 terms of either of the two licences - either the MPL alone or the GPL

 alone. However, we discourage people from distributing copies of NSS under

 the GPL alone, because it means that any improvements they make cannot be

 reincorporated into the main version of NSS. There is never a need to do

 this for license compatibility reasons.

 Note on LGPL Compatibility

 --------------------------

 The above also applies to combining MPLed code in a single library with

 code under the GNU Lesser General Public License (LGPL) version 2.1, or

 any later version of that license. If the LGPLed code and the MPLed code

 are not in the same library, then the copyleft coverage of the two

 licences does not overlap, so no issues arise.

 Mozilla Public License Version 2.0

 2. License Grants and Conditions

 --------------------------------

 2.1. Grants

 Each Contributor hereby grants You a world-wide, royalty-free,

 non-exclusive license:

 (a) under intellectual property rights (other than patent or trademark)

     Licensable by such Contributor to use, reproduce, make available,

     modify, display, perform, distribute, and otherwise exploit its

     Contributions, either on an unmodified basis, with Modifications, or

     as part of a Larger Work; and

 (b) under Patent Claims of such Contributor to make, use, sell, offer

     for sale, have made, import, and otherwise transfer either its

     Contributions or its Contributor Version.

 2.2. Effective Date

 The licenses granted in Section 2.1 with respect to any Contribution

 become effective for each Contribution on the date the Contributor first

 distributes such Contribution.

 2.3. Limitations on Grant Scope

 The licenses granted in this Section 2 are the only rights granted under

 this License. No additional rights or licenses will be implied from the

 distribution or licensing of Covered Software under this License.

 Notwithstanding Section 2.1(b) above, no patent license is granted by a

 Contributor:

 (a) for any code that a Contributor has removed from Covered Software;

     or

 (b) for infringements caused by: (i) Your and any other third party's

     modifications of Covered Software, or (ii) the combination of its

     Contributions with other software (except as part of its Contributor

     Version); or

 (c) under Patent Claims infringed by Covered Software in the absence of

     its Contributions.

 This License does not grant any rights in the trademarks, service marks,

 or logos of any Contributor (except as may be necessary to comply with

 the notice requirements in Section 3.4).

 2.4. Subsequent Licenses

 No Contributor makes additional grants as a result of Your choice to

 distribute the Covered Software under a subsequent version of this

 License (see Section 10.2) or under the terms of a Secondary License (if

 permitted under the terms of Section 3.3).

 2.5. Representation

 Each Contributor represents that the Contributor believes its

 Contributions are its original creation(s) or it has sufficient rights

 to grant the rights to its Contributions conveyed by this License.

 2.6. Fair Use

 This License is not intended to limit any rights You have under

 applicable copyright doctrines of fair use, fair dealing, or other

 equivalents.

 2.7. Conditions

 Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted

 in Section 2.1.

 3. Responsibilities

 -------------------

 3.1. Distribution of Source Form

 All distribution of Covered Software in Source Code Form, including any

 Modifications that You create or to which You contribute, must be under

 the terms of this License. You must inform recipients that the Source

 Code Form of the Covered Software is governed by the terms of this

 License, and how they can obtain a copy of this License. You may not

 attempt to alter or restrict the recipients' rights in the Source Code

 Form.

 3.2. Distribution of Executable Form

 If You distribute Covered Software in Executable Form then:

 (a) such Covered Software must also be made available in Source Code

     Form, as described in Section 3.1, and You must inform recipients of

     the Executable Form how they can obtain a copy of such Source Code

     Form by reasonable means in a timely manner, at a charge no more

     than the cost of distribution to the recipient; and

 (b) You may distribute such Executable Form under the terms of this

     License, or sublicense it under different terms, provided that the

     license for the Executable Form does not attempt to limit or alter

     the recipients' rights in the Source Code Form under this License.

 3.3. Distribution of a Larger Work

 You may create and distribute a Larger Work under terms of Your choice,

 provided that You also comply with the requirements of this License for

 the Covered Software. If the Larger Work is a combination of Covered

 Software with a work governed by one or more Secondary Licenses, and the

 Covered Software is not Incompatible With Secondary Licenses, this

 License permits You to additionally distribute such Covered Software

 under the terms of such Secondary License(s), so that the recipient of

 the Larger Work may, at their option, further distribute the Covered

 Software under the terms of either this License or such Secondary

 License(s).

 3.4. Notices

 You may not remove or alter the substance of any license notices

 (including copyright notices, patent notices, disclaimers of warranty,

 or limitations of liability) contained within the Source Code Form of

 the Covered Software, except that You may alter any license notices to

 the extent required to remedy known factual inaccuracies.

 3.5. Application of Additional Terms

 You may choose to offer, and to charge a fee for, warranty, support,

 indemnity or liability obligations to one or more recipients of Covered

 Software. However, You may do so only on Your own behalf, and not on

 behalf of any Contributor. You must make it absolutely clear that any

 such warranty, support, indemnity, or liability obligation is offered by

 You alone, and You hereby agree to indemnify every Contributor for any

 liability incurred by such Contributor as a result of warranty, support,

 indemnity or liability terms You offer. You may include additional

 disclaimers of warranty and limitations of liability specific to any

 jurisdiction.

 4. Inability to Comply Due to Statute or Regulation

 ---------------------------------------------------

 If it is impossible for You to comply with any of the terms of this

 License with respect to some or all of the Covered Software due to

 statute, judicial order, or regulation then You must: (a) comply with

 the terms of this License to the maximum extent possible; and (b)

 describe the limitations and the code they affect. Such description must

 be placed in a text file included with all distributions of the Covered

 Software under this License. Except to the extent prohibited by statute

 or regulation, such description must be sufficiently detailed for a

 recipient of ordinary skill to be able to understand it.

 5. Termination

 --------------

 5.1. The rights granted under this License will terminate automatically

 if You fail to comply with any of its terms. However, if You become

 compliant, then the rights granted under this License from a particular

 Contributor are reinstated (a) provisionally, unless and until such

 Contributor explicitly and finally terminates Your grants, and (b) on an

 ongoing basis, if such Contributor fails to notify You of the

 non-compliance by some reasonable means prior to 60 days after You have

 come back into compliance. Moreover, Your grants from a particular

 Contributor are reinstated on an ongoing basis if such Contributor

 notifies You of the non-compliance by some reasonable means, this is the

 first time You have received notice of non-compliance with this License

 from such Contributor, and You become compliant prior to 30 days after

 Your receipt of the notice.

 5.2. If You initiate litigation against any entity by asserting a patent

 infringement claim (excluding declaratory judgment actions,

 counter-claims, and cross-claims) alleging that a Contributor Version

 directly or indirectly infringes any patent, then the rights granted to

 You by any and all Contributors for the Covered Software under Section

 2.1 of this License shall terminate.

 5.3. In the event of termination under Sections 5.1 or 5.2 above, all

 end user license agreements (excluding distributors and resellers) which

 have been validly granted by You or Your distributors under this License

 prior to termination shall survive termination.

 *  Covered Software is provided under this License on an "as is"       *

 *  basis, without warranty of any kind, either expressed, implied, or  *

 *  statutory, including, without limitation, warranties that the       *

 *  Covered Software is free of defects, merchantable, fit for a        *

 *  particular purpose or non-infringing. The entire risk as to the     *

 *  quality and performance of the Covered Software is with You.        *

 *  Should any Covered Software prove defective in any respect, You     *

 *  (not any Contributor) assume the cost of any necessary servicing,   *

 *  repair, or correction. This disclaimer of warranty constitutes an   *

 *  essential part of this License. No use of any Covered Software is   *

 *  authorized under this License except under this disclaimer.         *

 *                                                                      *

 *  permitted above, be liable to You for any direct, indirect,         *

 *  special, incidental, or consequential damages of any character      *

 *  including, without limitation, damages for lost profits, loss of    *

 *  goodwill, work stoppage, computer failure or malfunction, or any    *

 *  extent applicable law prohibits such limitation. Some               *

 *  jurisdictions do not allow the exclusion or limitation of           *

 *  incidental or consequential damages, so this exclusion and          *

 *  limitation may not apply to You.                                    *

 *                                                                      *

 8. Litigation

 -------------

 Any litigation relating to this License may be brought only in the

 courts of a jurisdiction where the defendant maintains its principal

 place of business and such litigation shall be governed by laws of that

 jurisdiction, without reference to its conflict-of-law provisions.

 Nothing in this Section shall prevent a party's ability to bring

 cross-claims or counter-claims.

 9. Miscellaneous

 ----------------

 This License represents the complete agreement concerning the subject

 matter hereof. If any provision of this License is held to be

 unenforceable, such provision shall be reformed only to the extent

 necessary to make it enforceable. Any law or regulation which provides

 that the language of a contract shall be construed against the drafter

 shall not be used to construe this License against a Contributor.

 10. Versions of the License

 ---------------------------

 10.1. New Versions

 Mozilla Foundation is the license steward. Except as provided in Section

 10.3, no one other than the license steward has the right to modify or

 publish new versions of this License. Each version will be given a

 distinguishing version number.

 10.2. Effect of New Versions

 You may distribute the Covered Software under the terms of the version

 of the License under which You originally received the Covered Software,

 or under the terms of any subsequent version published by the license

 steward.

 10.3. Modified Versions

 If you create software not governed by this License, and you want to

 create a new license for such software, you may create and use a

 modified version of this License if you rename the license and remove

 any references to the name of the license steward (except to note that

 such modified license differs from this License).

 10.4. Distributing Source Code Form that is Incompatible With Secondary

 Licenses

 If You choose to distribute Source Code Form that is Incompatible With

 Secondary Licenses under the terms of this version of the License, the

 notice described in Exhibit B of this License must be attached.
